Laser tile machining process

A three-dimensional laser machining process is being developed to cut replacement tiles for the Space Shuttle. The process involves a carbon dioxide laser and a computer-controlled five-axis positioner. To date, successful straight-through cuts, curved-through cuts, and partial cuts have been made by the laser. Felt reusable surface insulation, another component of the Shuttle's thermal protection system, has also been successfully cut using the laser. At the conclusion of research, if successful, a production version of the laser machining process will be implemented by Lockheed at the Kennedy Space Center.<
